Specification of Letters Patent.

Application filed December 12, 1910. Serial No. 596,814.

To all whom it may concern Be it known that I, DAVID SAMMEL, a citizenof the United States, residing at A1 toona, in the county of Blair andState of 5 Pennsylvania, have invented certain new and sures as is nowcommonly done, to a mini-.

mum.

A further object of the invention is to provide a closure into which theexhaust steam from the air pumps may pass and in which the -oil in thesteam, together with the water, may be collected, thereby making aneffective water back, against which the gaseous flames emerging from thefront ends of the boiler fi'ues, will impinge.

A still further object of the invention is invention consists in theconstruction and novel combination of parts hereinafter fully described,illustrated in the accompanying drawings, and pointed out in the claimshereto appended; it'being understood that various changes in the form,proportion, size and minor details of construction, within the scope ofthe claims, may be resorted to without departing from the spirit orsacrificing any of the advantages of the invention.

In the drawings :-Figure 1 is a side elevation of a front end of alocomotive, showing my improved closure applied thereto.

in'Fig. 1. Fig. 3 is an enlarged edge view of the smoke box closure.Fig. 4 is a sectional view of the closure shown in Fig. 8.

Fig. 5 is a detail sectional view taken on the 1 line 5-5 of Fig, 4.Fig. 6 is a detail secto provide a closure having a connection.

I tional view taken on the line 6-6 of Fig. 4.

Fig. 7 is an enlarged sectional view taken on the line 7--7 of Fig. 2,and showing the manner of forming the air tight connection between theclosure and the front end of a smoke box, and Fig. 8 is an enlargeddetail sectional view showing a modification.

Like reference numerals designate corresponding parts in all the figuresof the drawings.

Referring to the drawings, the reference numeral 10 designates the usualsmoke box of a locomotive in which are located the ordinary parts, notshown, such as, for instance, the exhaust nozzle and the steam supplypipes, etc.

My invention comprises a front end 11 which is secured to a ring 12 bymeans of a bolt 13, said ring 12 being carried by the end of the smokebox 10. This front end is of a semi-conical formation, and is providedat its forward end with an opening 11*, through which access to theboiler tube may be made. The forward edge of the front end 11 isenlarged as shown by numeral 14, and is provided with a seat 15, inwhich is located a gasket 16. Formed on the ex terior of the front end11, is a plurality of spaced pairs of cars 17 and between each pairthereof is journaled a bolt 18, as will be readily understood by thoseskilled in the art.

The invention further comprises a closure designated as a whole by thenumeral 19, for the opening 11 this closure consisting of acomparatively shallow drum formed of front and rear walls 20 and 21respectively, and a connecting web 22. Integral with Patented. Apr. 9,1912.

the said connecting web and extending therebolts 18 are swung downwithin the bifur.

cated stops 23 and, means of a nut 25, the closure 19 can bequicklyconnected or disconnected to or from the said front end. This closure'isfurthermore provided with hinged members 26- 26 which coact with hingemembers 27 carried by the front end. The closure 11 is furthermoreprovided with vertically arranged spaced partitions 28,

which extend from the bottom of the drum 1 and terminate at a pointbelow the top thereof. These partitions connect the walls 20 and 21 andthereby form a passage or stand-pipe 29 having an upper open end 30. Theclosure furthermore comprises interior walls 31 which are arranged inspaced relation to the connecting web 22 to form passages 31 These walls31 extend from the bottom of the transverse walls 28 and terminate inthe top of the closure above the open end 30 of the passage 29, as shownby reference numerals 32.

Exhaust pipes 33 for the air pumps are connected by a T 34 and said Tcommunicates with the passage 29 by means of a pipe 35.

Respectively connecting each of the passages 31 are pipes 36 which areconnected to the relief valves 37, said relief valves being connected tothe steam chest 38.

From the foregoing, it will be observed that the exhaust steam from theair pumps will pass from the pipes 33, the T 34, pipe 35, and into thepassage 29 of the closure. The water of condensation will accumulate inthe passage 19 and the steam in the clo sure will pass out through theexhaust 39. It is a well known fact that considerable oil is carriedaway by the steam. As the water accumulates in the passage 29, it willeventually flow over the open end 30 and down the outside thereof andfill the space between the transverse partitions 28 and the partitions32. The oil contained in the steam will of course float on the water,and

as the volume of water increases, the oilwill eventually flow over theends 32 of the partitions 31 and into the passages 31 From thence theoil will flow through the pipes 36, past the relief valves 37 and intothe steam chest 38. Thus it will be observed that this oil, which wouldordinarily be wasted, will be used for lubricating the valves and thecylinders, stopping the groaning of the valves and avoiding the cuttingof the cylinders.

The closure is also provided with openings 40 formed in the rear wall21, whereby the steam contained in the closure may escape into the smokebox. The closure or drum is also provided with a stop cook 41 arrangednear the bottom thereof and adapted to permit the egress of the waterwhen, for instance, the locomotive is standing still. Thus all danger ofthe water freezing can be avoided.

Should it be desired to attach the closure directly to the end of thesmoke box 10, the construction shown in Fig. 8 of the drawing may beemployed. In this structure, the smoke box 10 is provided at its endwith a ring 12 which is secured in position by suitable means. Formed insaid ring and communicating with the outer face 12 thereof is acontinuous recess 13 and in this recess is arranged a gasket 14 Formedon the exterior of the front end of the smoke box proper is a pluralityof spaced pairs of cars 17 and between each pair thereof is journaled abolt 18 The closure 19 is formed in the same manner as the door 19,before described, and is provided with a marginal rib 24k which projectsinto the recess 13 and bears against the said gasket 14 This door ishingedly mounted on the smoke box in any well known manner, and isprovided with a plurality of bifurcated stops 23" adapted to receive thebolts 18, as will be readily understood.
